Transjugular intrahepatic portosystemic shunts in liver transplant recipients

Abstract

The insertion of a transjugular intrahepatic portosystemic shunt (TIPS) is a minimally invasive procedure used to relieve the signs and symptoms of portal hypertension in patients with liver disease. The most common indications for placement are refractory ascites and variceal hemorrhage. In properly selected candidates, TIPS placement can serve as a bridge to liver transplantation. Expertise in TIPS placement after transplantation has significantly increased, which has allowed the procedure to become a viable option for retransplant candidates suffering the consequences of recurrent portal hypertension due to portal vein thrombosis, recurrent liver disease, or hepatic venous outflow obstruction (HVOO). However, TIPSs in liver transplant recipients are associated with a lower clinical response rate and a higher rate of complications in comparison with patients with native liver disease, and they are, therefore, generally reserved for patients with a Model for End-Stage Liver Disease (MELD) score ≤ 15 and ≤ 12 in patients with HCV. The role of TIPS placement in nonliver transplant recipients has been well studied in large trials, and it translates well into clinical applicability to candidates for orthotopic liver transplantation (OLT). However, the experience with OLT recipients is heterogeneous and restricted to small series. Thus, we focus here on reviewing the current literature and discussing the proper use of TIPSs in liver transplant recipients. © 2013 American Association for the Study of Liver Diseases.
